金川铜镍(铂)硫化物矿床以体积小、储量大闻名于世,其独特的地质特征一直倍受中外地质学家的关注。近年来,随着勘探程度与资料积累不断加深,对金川矿床的研究取得很大进展,金川超基性岩体以F16-1断层为界的东、西岩体,在岩相学、矿物学、地球化学特征上差异显著,根据橄榄石粒径大小,西岩体可以划分为上部中细粒、下部中粗粒岩相带,从地球化学特征来看,西岩体上、下两个岩相带的无矿岩石具有不同的演化趋势,而东岩体所有无矿岩石具有一致的趋势,这些都表明了东、
The Jinchuan copper-nickel (platinum) sulfide deposit is famous for its small size and large reserves. Its unique geological features have always been the focus of Chinese and foreign geologists. In recent years, with the deepening of the degree of exploration and the accumulation of data, great progress has been made in the research on the Jinchuan deposit. The Jinchuan ultramafic rocks are characterized by lithofacies and mineralogy , The geochemical characteristics of the significant differences, according to the size of the olivine, the West Rock body can be divided into the upper part of the fine grain, the lower part of the coarse grained facies, from the geochemical characteristics of the West Rock body, the next two rocks The non-ore-bearing rocks in the belt have different evolutionary trends, and all the ore-free rocks in the East Rock body have a consistent trend, indicating that the East,
